    Cold to Exit then Return

    Friday 10:45 a.m.

    Here is the morning video, and I was dressed for the occasion:

    A fast-moving storm will spread snow to the East Coast by the end of the day. Most of the accumulations have been light, but heavy snow broke out in southwestern and central Ohio. The Dayton area picked up a quick 3 inches. The map below shows the pressure pattern at 10 a.m. EST. The close spacing of lines from northern Georgia to West Virginia implies strong winds heading north. However, on a line from central Kentucky to northern West Virginia, the lines quickly spread apart, There and just to the north is the area where the heaviest precipitation was breaking out.

    Computer models suggest this enhanced snow will continue eastward to the middle of Pennsylvania then weakens. There will be updates of stories and videos on AccuWeather.com all afternoon and evening. The main thing this morning was how little snow it has taken to cause nasty travel conditions. The Chicago morning rush hour was a nightmare when most places had about a half inch of snow. The total Chicago snowfall surpassed 1 inch for the first time this season. The last time they had that much was one month less than a year ago.

    As milder air advances northeastward, it will run into the retreating cold air. This could lead to assortment of precipitation types, with freezing rain posing the greatest danger. As the mild air flows over the cold ground, areas of dense fog could develop.

    Later next week, cold will regain its place in the Great Lakes and Northeast and mildness will be in the shadows on Groundhog Day.
